1) Read this article about the Death of the English language.
Now keep this is mind. The Gutenberg press didn’t make the scene until the 15th century.
So the stories in the Bible relied on either hand copying aka scribing but prior to that were aural only. Even today lots of people get their biblical knowledge from pastors, the same pastors who have their own agendas just like old Saul of Tarsus aka St. Paul. I suspect the mutt had a stroke because he had a sudden ephiphany and wrote his misogynistic and homophobic screed.
It’s all bullshit.
Spewing Truth in the face of Lies 
I agree with you about the Bible not being the infallible Word of God; I’ve said it for years. I do believe however that it contains some things of worth (love thy neighbor, for example).
A stroke seems unlikely. Perhaps his schizophrenia got the best of him.
I agree that we bloggers, and any writer with a public forum, should be more careful about grammar and punctuation. We all make errors in typing from time to time, but not knowing the difference between “then” and “than” is inexcusable. It’s one of the misuses that make me cringe as I read.
As for the title of your post: an endless conversation could be had just attempting to arrive at consensus regarding the meaning of the words “believe”, “bible”, “word” and “god”. Despite its various permutations over the centuries “the bible” has survived – perhaps because it touches on universal themes and the fundamental characteristics of the human condition with wisdom, controversy, compassion, etc. Whether it is/was “divinely inspired” is part of that endless conversation.
